REALTORS® & Sustainability Report
REALTORS® & Sustainability Report (National Association of REALTORS®, Sept. 2025)
In April 2025, NAR surveyed its members about sustainability issues facing the residential real estate industry. The findings are as follows:
- Client interest in energy efficiency is increasing. 42% said clients rarely ask about energy upgrades, a steep rise from seven percent in 2024. Those reporting that clients never ask declined from 57% to 29%.
- Green MLS data is underutilized. 44% said their MLS includes green data fields, but nearly half (47%) of those with access do not use them.
REALTORS® Answer Questions about Climate Risk
Script for REALTORS® on Climate Risk (Sustainability Advisory Group, 2023)
“In 2023, the Sustainability Advisory Group requested this material to be placed on the NAR’s Sustainability webpage to help NAR members answer questions from consumers, clients and potential homebuyers about the risks of climate change in their community. This “script” will help members guide consumers to the information they need to make informed decisions about their property purchase.”
Sustainability and Real Estate
A Tale of Two Towns: A Case Study on Building Communities with Sustainability and Resiliency at the Forefrontpdf (Sustainability Advisory Group, Nov. 2024)
“In 2018, the Sustainability Advisory Group (SAG) was created to “evaluate, monitor, analyze, and implement means and methods for integrating sustainability into all aspects of residential and commercial real estate… [and to] provide information and proposed resources on sustainability-related issues to the NAR Leadership Team. “As part of their work providing information on sustainability-related issues, the SAG is exploring the impact of major natural disaster events on the local housing market and REALTOR®’s livelihood. In 2024, the SAG chose to do a case study of two communities: Greensburg, Kansas and Babcock Ranch, Florida. The research focuses on the sustainable rebuilding of Greensburg, Kansas after it was leveled by a tornado and the building of Babcock Ranch, Florida from the ground up to serve as a model sustainable and resilient community in the face of Florida’s weather extremes. The research focuses on sustainable and resilient policies and building practices in residential, commercial, and town infrastructure, as well as the ways each town harnessed their most abundant renewable resources. Finally, the case study discusses opportunities, challenges, and actions for REALTORS® to be advocates for sustainable building in their communities.”
NAR Sustainability Advisory Group Market Transformation White Paperpdf
“Written by the National Association of REALTORS Sustainability Advisory Group, with input from the Appraisal Institute and the Council of Multiple Listing Services, recommends specific actions for state energy offices to consider when creating their Inflation Reduction Act rebate programs and required Market Transformation Plan. It includes a list of resources and tools already in the market that could scale with the programs. It also includes suggested strategies for partnering with REALTOR associations and other stakeholders to increase the impact of the rebate programs and solve for specific challenges agents face.”
How Climate Risks are Impacting Real Estate Insurance Costs (JLL, Jan. 23, 2025)
“In the U.S., insurance is the fastest growing line item for building owners, with knock-on effects for operating incomes and longer-term asset values. In some high-risk coastal regions such as California and Florida, insurers have exited some local markets or limited their coverage following years of escalating losses. State-sponsored programs such as California’s FAIR plan are a last resort, but the Los Angeles wildfires have raised questions over whether they can cover huge damage bills.
“Rising insurance costs are becoming a significant challenge for real estate owners, especially in markets facing direct climate hazards. Insurers traditionally accounted for a 2-3% annual increase in expenses, but premiums are rising much faster, driven by the escalating financial toll of climate events,” says Jaime del Álamo, Head of ESG Value & Risk Americas, JLL.”
Smart Buildings Keep Getting Smarter (CCIM, Fall 2024)
“Building owners/operators want to improve energy efficiency and lower operational costs, meet environmental regulations and ESG goals, enhance occupant safety/comfort, and provide digital amenities to draw tenants. All this makes a building more attractive to occupants and investors and boosts property value. "I think smart buildings are the future of office and commercial real estate in general," says Galvan. "There are so many aspects of intelligent infrastructure," says Timothy Churchwell, CCIM, Vice President of TEC Holdings, LLC. "A fire breaks out, and the elevator immediately shuts down, so safety issues exist. There are economic issues. There are energy efficiency issues." He says smart building technology is a must-have, especially in new construction. According to a recent Precedence Research report, the smart building technology market is booming and anticipated to expand at a CAGR of 10.9%, reaching $256.18 billion by 2033.”
UN Global Status Report for Buildings and Construction (United Nations Environmental Programme, Mar. 2024)
“The buildings and construction sector contributes significantly to global climate change, accounting for about 21 per cent of global greenhouse gas emissions. In 2022, buildings were responsible for 34 per cent global energy demand and 37 per cent of energy and process-related carbon dioxide (CO2) emissions. Despite a 3.5 per cent reduction in energy intensity, overall energy demand and emissions rose by about one per cent from 2021. Policy progress is evident with more comprehensive climate action plans covering buildings and construction in Nationally Determined Contributions (NDCs). However, few align with net-zero operational emissions, and while over 81 countries have building energy codes, many are outdated. Looking forward to 2024, the focus must be on tangible emission reductions, enhancing building performance, increasing renewable energy use and addressing housing and energy access disparities. Despite the complexities, strategic partnerships can facilitate the shift to an efficient, resilient and whole life net-zero carbon global building stock.”
Disaster in Paradise (Sustainability Advisory Group, Nov. 2023)
“In 2018, the Sustainability Advisory Group(SAG) was created to “evaluate, monitor, analyze, and implement means and methods for integrating sustainability into all aspects of residential and commercial real estate...[and to] provide information and proposed resources on sustainability-related issues to the NAR Leadership Team.” As part of their work providing information on sustainability-related issues, the SAG is exploring the impact of major natural disaster events on the local housing market and REALTOR®’s livelihood… in 2023 the SAG chose to study the impact of the 2018 Camp Fire on the housing of Paradise, California. The research focused on housing supply and price impacts, but the SAG chose to extend their research and pursue three central topics: 1. the ways the power grid infrastructure contributed to the fire and the role of power companies in natural disasters; 2. The preparedness of the community for a wildfire disaster; and 3. the rebuilding effort, particularly focusing on building codes, resilient building, and property maintenance.”
